Specs
• The coloring of results in the network statistics pages (see MoCA Network Statistics on page 7-9)
• Pass/marginal/fail determinations during the MoCA Quick Test (see MoCA Quick Test on page 7-23)
• Certain other behaviors of the MoCA Quick Test
Thresholds are specified as ranges, such as “Pass” ranges and “Fail” ranges. For coloring and
evaluations related to thresholds, the unit uses:
• Red/Fail for a metric that falls within the “Fail” range
-or-
If the respective threshold does not include a “Fail” range, a metric that falls outside the “Pass” range
• Yellow/Marginal for a metric that falls within a “Marginal” range, if the respective threshold includes
such a range
• Green/Pass (or no coloring) for a metric that falls within the “Pass” range
Additionally, note the following:
• When specifying thresholds, the unit enforces theoretical/technical limitations. For example, a bit rate
cannot be less than zero. In general, if the inherent lower or upper range of a threshold represents a
technical limit, the unit restricts the editing of the field altogether.
• For thresholds with pass, marginal, and fail ranges, the unit enforces continuity between the ranges,
normally by disallowing the editing of certain fields. For example, the marginal Bit Rate range is
automatically determined by the lower Pass and upper Fail values and is therefore restricted from
editing.
• In the Enabled column, you can disable any specific threshold which causes the threshold to have no
effect on coloring or pass/fail evaluations. This feature may be useful for situations where testing with
the unit is required but a final determination of appropriate pass/fail criteria has not yet been made.
The following table describes the supported thresholds.
Bit Rate
CP Len
Phase Offset
Log Gain Mean
Power Adjust
Determine the valid range for the respective parameters in the Node Stats
pages and for the corresponding stages during a MoCA Quick Test (see
Node Stats page (MoCA Network Statistics) on page 7-13). Additionally, the
Bit Rate ranges determine the valid ranges for the bit rates between any
two devices during the retrieval of the bandwidth table (see Bandwidth
page (MoCA Network Statistics) on page 7-10).
Bit Loading (%)
Bit Loading (bits)
Together, determine when a bit loading profile is sufficiently robust, used for
pass/fail evaluations during the MoCA Quick Test. If at least the specified
percentage of subcarriers are carrying at least specified number of bits, the
bit loading is considered passing. Otherwise, it is considered a failure.
For general information on bit loading, see Node Stats page (MoCA
Network Statistics) on page 7-13.
